Can anyone think of (better yet link to) examples of CBAs done by EAs where at least one of the options is an everyday (or at least common enough to be familiar to the average guy on the street) traditionally 'ethical', or at least prudential one. Egs that I know of include the Planes vs Trains thread I've just put up, anything on the replaceability effect, Rob Wiblin's blog on buying better equipment.

I'm sure Brian had something on the value(or lack thereof) of 'ethical' investment, but I can't find it now, and it seems like there must be a number of such posts around. Back-of-the-envelope type stuff is fine. I'm just after as many examples as possible

Ta Ryan. To clarify (edited the OP to make this clear) I'm looking for examples where we're looking at questions that will be familiar to non-EA people, or people recently coming to EA, so funding AI doesn't really fall under the scope.
